<P>
    The Boost Iostreams library provides two types of Filters for text processing: <A href="../classes/regex_filter.html">Regular Expression Filters</A>, which use the  <A HREF="http://www.boost.org/libs/regex" TARGET="_top">Boost Regular Expression Library</A> (<A CLASS="bib_ref" href="../bibliography.html#maddock">[Maddock]</A>) to perform text substitutions, and <A href="../classes/newline_filter.html">Newline Filters</A>, which convert between the text file formats used by various operating systems.
